RE: [xsl] namespace dynamic declaration

---

In XSLT 2.0 you can do this with the new <xsl:namespace> instruction. In
XSLT 1.0 it's more difficult. What you have to do is to create a
temporary tree that contains an element in the required namespace; this
will automatically create a namespace node for that namespace, and you
can then copy this namespace node (with the help of the xx:node-set()
extension function) to your result tree:

<xsl:variable name="dummy">
<xsl:element name="myprefix:dummy" namespace="{$param}"/>
</xsl:variable>

<xsl:copy-of select="exslt:node-set($dummy)//namespace::*/>

If you don't mind having an unwanted attribute in the result tree, an
easier method is to create an attribute whose name in the desired
namespace, which will automatically create an associated namespace node.
